Abstract

The MHD wave instability in commercial cells for electrolyticaluminium production is often described using ‘shallow water’models. The model [1] is extended for a variable height cathode bottom and anode top to account for realistic cell features. The variable depth of the two fluid layers affects the horizontal current density, the wave development and the stability threshold. Instructive examples for the 500 kA cell are presented.
